Ladies and Gentlemen:

Citibank Credit Card Issuance Trust, a Delaware statutory trust (the “Issuer”), proposes to sell, and Citibank, N.A. (“Citibank”), as the owner of all the beneficial interests in the Issuer, proposes to cause the Issuer to sell, to the underwriters named in Schedule I hereto (the “Underwriters”) for whom you are acting as representative (the “Representative”), the aggregate principal amount of notes of the Citiseries designated above and in Schedule III hereto (the “Notes”), subject to the provisions of this Underwriting Agreement (this “Agreement”) among the Issuer, Citibank, and the Underwriters.

Citibank has conveyed and proposes to continue to convey credit card receivables (the “Receivables”) arising from revolving credit card accounts and other rights to the Citibank Credit Card Master Trust I (the “Master Trust”). Citibank, as Seller and Servicer, and Deutsche Bank Trust Company Americas, as trustee (the “Master Trust Trustee”) have entered into the Third Amended and Restated Pooling and Servicing Agreement, dated as of November 10, 2016 (as modified or amended from time to time, the “Base P&S”), and the Amended and Restated Series 2000 Supplement to the Base P&S, dated as of September 26, 2000, as amended and restated as of August 9, 2011 and as amended by Amendment No. 1 as of November 10, 2016 (as modified or amended from time to time, the “Series 2000 Supplement”). The Base P&S and the Series 2000 Supplement are referred to herein collectively as the “Pooling and Servicing Agreement”. Pursuant to the Pooling and Servicing Agreement, Citibank caused the Master Trust to issue to the Issuer a Credit Card Participation Certificate, Series 2000 (the “Collateral Certificate”). The Collateral Certificate represents undivided interests in certain assets of the Master Trust. Certain of the Receivables (and the related Accounts) will be subject to review by FTI Consulting, Inc. (the “Asset Representations Reviewer”) in certain circumstances for compliance with certain representations and warranties made about the Receivables, in accordance with the Asset Representations Review Agreement, dated as of November 18, 2016 (as amended or supplemented from time to time, the “Asset Representations Review Agreement”), between Citibank and the Asset Representations Reviewer.

The Notes will be issued pursuant to the Second Amended and Restated Indenture, dated as of November 10, 2016 (as modified or amended from time to time the “Indenture”), between the Issuer and Deutsche Bank Trust Company Americas, as trustee (the “Indenture Trustee”). The Notes will be secured by certain assets of the Issuer and will be sold pursuant to this Agreement.

Capitalized terms used in this Agreement that are not defined herein have the meanings provided in the Indenture, or if not defined therein, in the Pooling and Servicing Agreement. The Pooling and Servicing Agreement, the Asset Representations Review Agreement, the Trust Agreement, the Indenture, any Derivative Agreement relating to the Notes, the Depository Agreement between the Issuer and The Depository Trust Company (“DTC”) and this Agreement are collectively referred to as the “Basic Documents”.

(x) Rule 17g-5. In connection with any rating for the Notes, Citibank has provided a written representation (the “17g-5 Representation”) to each rating agency or rating agencies rating the Notes (each, a “Note Rating Agency”) that satisfies the requirements of paragraph (a)(3)(iii) of Rule 17g-5 under the Exchange Act (“Rule 17g-5”).

In reaching this conclusion, the Issuer has relied primarily on the determination that (i) the Issuer may rely on the exclusion from the definition of “investment company” set forth in Rule 3a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”), and accordingly, (ii) the Issuer may rely on the exclusion from the definition of a “covered fund” under the ▇▇▇▇▇▇▇ Rule of an issuer that may rely on an exclusion or exemption from the definition of “investment company” under the Investment Company Act other than the exclusions contained in Sections 3(c)(1) and 3(c)(7) of that Act.

(aa) Due Diligence Services or Reports. Citibank has not engaged, or caused any other person to engage, any third party to provide “due diligence services” within the meaning of Rule 17g-10(d)(1) under the Exchange Act or obtained any third-party due diligence report within the meaning of Rule 15Ga-2(d) under the Exchange Act with respect to the assets held by the Issuer in connection with the offering of the Notes.

(bb) U.S. Risk Retention. Citibank has complied with all requirements imposed on the “sponsor” in accordance with the final rules contained in Part 244 – Credit Risk Retention (Regulation RR), 12 C.F.R. §§244.1-244.22, (as the same may be amended from time to time, the “U.S. Credit Risk Retention Rules”), implementing the credit risk retention requirements of Section 15G of the Exchange Act. Citibank’s Sellers’ Interest under the Pooling and Servicing Agreement constitutes a “seller’s interest” as defined in Section 244.5(a) of the U.S. Credit Risk Retention Rules. Citibank complies with the credit risk retention requirements through retention by Citibank of an interest in the

Sellers’ Interest in an amount equal to not less than 5% of the aggregate unpaid principal balance of all outstanding investor “ABS interests” (as defined in Section 244.2 of the U.S. Credit Risk Retention Rules), in the Issuer issued as part of the transactions contemplated by the Basic Documents, with such adjustments, if any, as may be permitted or required in accordance with the U.S. Credit Risk Retention Rules, measured as of the Closing Date in accordance with the U.S. Credit Risk Retention Rules (such interest, the “Retained Interest”).

(cc) EU-UK Risk Retention. As used in this agreement, (i) “EU securitization regulation” refers to Regulation (EU) 2017/2402 of the European Parliament and of the Council of 12 December 2017 laying down a general framework for securitization and creating a specific framework for simple, transparent and standardized securitization and amending certain other European Union (“EU”) directives and regulations, as amended from time to time, and (ii) “UK securitization framework” refers to The Securitisation Regulations 2024 (as amended, the “SR 2024”), together with (i) the securitisation sourcebook of the handbook of rules and guidance adopted by the Financial Conduct Authority of the UK (the “SECN”), (ii) the Securitisation Part of the rulebook of published policy of the Prudential Regulation Authority of the Bank of England (the “PRASR”) and (iii) relevant provisions of the Financial Services and Markets Act 2000, as amended, setting out the framework for the regulation of securitization in the UK, and as may be further amended, supplemented or replaced from time to time.

Citibank covenants and agrees to retain a material net economic interest that is not less than 5% of the nominal value of the securitized exposures (measured at origination), in a form that is intended to qualify as an originator’s interest as provided in option (b) of Article 6(3) of the EU securitization regulation as in effect on the date of issuance of the Notes by holding all or part of the Sellers’ Interest. Citibank further covenants and agrees to retain a material net economic interest that is not less than 5% of the nominal value of the securitized exposures (measured at origination), in a form that is intended to qualify as an originator’s interest as provided in paragraph (1)(b) of SECN 5.2.8R and Article 6(3)(b) of Chapter 2 of the PRASR as in effect on the date of issuance of the Notes, by holding all or part of the Sellers’ Interest.

Delivery of one or more global notes representing the Notes will be made to the accounts of the several Underwriters against payment by the several Underwriters of the

purchase price therefor to or upon the order of Citibank by one or more wire transfers or checks in Federal (same day) Funds. The global notes to be so delivered will be registered in the name of Cede & Co., as nominee for DTC. The interests of beneficial owners of the Notes will be represented by book entries on the records of DTC and participating members thereof.

(b) Each Underwriter, severally but not jointly, agrees to indemnify and hold harmless the Issuer, Citibank, each of its directors, each of the officers who signs the Registration Statement, and each person who controls the Issuer or Citibank within the meaning of the Securities Act, to the same extent as the foregoing indemnities from the Issuer and Citibank to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Issuer or Citibank by or on behalf of such Underwriter specifically for use in the preparation of the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. [The Issuer and Citibank acknowledge that the statements relating to the Underwriters and this Agreement set forth in the second sentence under the heading “Risk Factors—Your ability to resell notes may be limited”, the statements in the first paragraph (including the information in the table), and the second, fourth, sixth, eighth, ninth, tenth, eleventh, twelfth and thirteenth paragraphs under the heading “Underwriting (Plan of Distribution, ▇▇▇▇▇▇▇▇ and Conflicts of Interest)” and the statements under the subheading “Offering Restrictions” under the heading “Underwriting (Plan of Distribution, Proceeds and Conflicts of Interest)” in the Preliminary Prospectus and the Prospectus constitute the only information furnished in writing by or on behalf of any Underwriter for inclusion in any Issuer Free Writing Prospectus, Preliminary Prospectus or the Prospectus, and each Underwriter confirms that such statements are correct.]¹

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under this Section 8. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled, jointly with any other indemnifying party similarly notified, to appoint counsel satisfactory to such indemnified party to represent the indemnified party in such action; provided, that if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties will have the right to select separate counsel to assert such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election so to appoint counsel to defend such action and approval by the indemnified party of such counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party has employed separate counsel in connection with the assertion of legal defenses in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying

¹	[To be confirmed as necessary.]

party will not be liable for the expenses of more than one separate counsel, approved by the Underwriters in the case of paragraph (a) of this Section 8, representing the indemnified parties under such paragraph (a) who are parties to such action), (ii) the indemnifying party has not employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party; and except that, if clause (i) or (iii) is applicable, such liability will be only in respect of the counsel referred to in such clause (i) or (iii).

(d) To provide for just and equitable contribution in circumstances in which the indemnification provided for in paragraph (a) of this Section 8 is due in accordance with its terms but is for any reason held by a court to be unavailable on grounds of policy or otherwise, the Issuer and Citibank, on the one hand, and the Underwriters, on the other, will contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) to which the Issuer, Citibank and the Underwriters may be subject in such proportion so that the Underwriters will be responsible for that portion represented by the percentage that the underwriting discount appearing on the cover page of the Prospectus bears to the public offering price appearing thereon and the Issuer and Citibank will be jointly and severally responsible for the balance; provided, that (i) in no case will any Underwriter (except as may be provided in the agreement among underwriters relating to the offering of the Notes) be responsible for any amount in excess of the underwriting discount applicable to the Notes purchased by such Underwriter hereunder and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls any Underwriter within the meaning of the Securities Act will have the same rights to contribution as such Underwriter, and each person who controls the Issuer or Citibank within the meaning of the Securities Act, each officer of the Issuer or Citibank who has signed the Registration Statement and each director of Citibank will have the same rights to contribution as the Issuer and Citibank, as the case may be, subject in each case to clauses (i) and (ii) of this paragraph (d). Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against any other party or parties under this paragraph (d), notify such party or parties from whom contribution may be sought, but the omission to so notify such party or parties will not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have hereunder or otherwise than under this paragraph (d).

SECTION 9. Termination. This Agreement will be subject to termination in the absolute discretion of the Underwriters, by notice given to the Issuer and Citibank before delivery of and payment for the Notes, if before such time (i) trading in securities generally on the New York or, if applicable, the European Exchange will have been suspended or limited, (ii) a banking moratorium will have been declared by federal, New York, or South Dakota state authorities or (iii) there will have occurred any outbreak or material escalation of hostilities or other calamity or crisis the effect of which on the financial markets of the United States of America, Japan or Europe is such as to make it, in the judgment of the Underwriters, impractical or inadvisable to market the Notes.

The Issuer and Citibank agree that they will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Issuer or Citibank, in connection with such transaction or the process leading thereto.

SECTION 15. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Issuer, Citibank and the Underwriters, or any of them, with respect to the subject matter hereof.

SECTION 16. No Waiver; Headings. Neither this Agreement nor any term hereof may be changed, waived, discharged or terminated orally, but only by an instrument in writing signed by the party against whom enforcement of the change, waiver, discharge or termination is sought. The headings in this Agreement are for purposes of reference only and will not limit or otherwise affect the meaning hereof.

SECTION 17. Default by an Underwriter. If any one or more Underwriters fail to purchase and pay for any of the Notes agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase constitutes a default in the performance of its or their obligations under this Agreement, the remaining Underwriters will be obligated severally but not jointly to take up and pay for (in the respective proportions which the amount of Notes set forth opposite their names in Schedule I hereto bears to the aggregate amount of Notes set forth opposite the names of all the remaining Underwriters) the Notes which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, that if the aggregate amount of Notes which the defaulting Underwriter or Underwriters agreed but failed to purchase exceeds 10% of the aggregate principal amount of Notes set forth in Schedule I hereto, the remaining Underwriters will have the right to purchase all, but will not be under any obligation to purchase any, of the Notes, and if such nondefaulting Underwriters do not purchase all the Notes, this Agreement will terminate without liability to any nondefaulting Underwriter, the Issuer or Citibank. In the event of a default by any Underwriter as set forth in this Section 17, the Closing Date will be postponed for such period, not exceeding seven days, as the Underwriters determine in order that the required changes in the Registration Statement and the Prospectus (and any supplements thereto) or in any other documents or arrangements may be effected. Nothing contained in this Agreement will relieve any defaulting Underwriter of its liability, if any, to the Issuer, Citibank and any nondefaulting Underwriter for damages occasioned by its default hereunder.

SECTION 18. Representations of Underwriters.

(a) The Representative will act for the several Underwriters in connection with this financing, and any action under this Agreement taken by the Representative will be binding upon all the Underwriters.

(b) Each Underwriter, severally but not jointly, represents that it has not and covenants that it will not provide any oral or written Rating Information (as defined below) to a Note Rating Agency or other “nationally recognized statistical rating organization” (within the meaning of the Exchange Act), unless a designated representative from Citibank participated in or participates in such communication; provided, however, that if an Underwriter received or receives an oral communication from a Note Rating Agency, such Underwriter was and is authorized to inform such Note Rating Agency that it will respond to the oral communication with a designated representative from Citibank or refer such Note Rating Agency to Citibank, who will respond to such oral communication. For purposes of this paragraph, “Rating Information” means any information provided for the purpose of determining the initial credit rating for the Notes or undertaking credit rating surveillance on the Notes (as contemplated by paragraph (a)(3)(iii)(C) of Rule 17g-5) including, but not limited to, information about the characteristics and performance of the Receivables.

SECTION 19. No Personal Liability of Issuer Trustee. The obligations of the Issuer under this Agreement are not personal obligations of the Issuer Trustee and, consequently, the Issuer Trustee does not have any personal liability for any amounts required to be paid by the Issuer under this Agreement.

SECTION 20. No Petition. Each Underwriter agrees that it will not, before the date that is one year and one day after the date on which all notes or securities issued by the Issuer have been paid in full, acquiesce, petition or otherwise invoke or cause the Issuer to invoke the process of any governmental authority for the purpose of commencing or sustaining a case against the Issuer under any federal or state bankruptcy, insolvency or similar law or appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator or other similar official of the Issuer or any substantial part of its property or ordering the winding-up or liquidation of the Issuer.

SECTION 21. Recognition of the U.S. Special Resolution Regimes.

(a) Notwithstanding any other term of this Agreement or any other agreements, arrangements, or understanding between the parties hereto, Citibank, the Issuer and each of the Underwriters acknowledges, accepts, and agrees to be bound by the following:

(i) In the event that Citibank, the Issuer or any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such entity of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(ii) In the event that Citibank, the Issuer or any Underwriter that is a Covered Entity or a BHC Act Affiliate of such entity becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such entity are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

Subject to the immediately preceding provisions, and notwithstanding any other term of this Agreement or any other agreements, arrangements, or understanding between the parties hereto, each Underwriter acknowledges, accepts, and agrees that (A) it may exercise Default Rights under this Agreement only to the extent permitted and as provided under 12 C.F.R. § 252.84 and (B) after a BHC Act Affiliate of a party that is a Covered Entity has become subject to Insolvency Proceedings, it shall have the burden of proof, by clear and convincing evidence, that the exercise of such Default Right is permitted hereunder.

(b) As used in this Section 21, “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k); “Covered Entity” means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b), (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b) or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b); “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§

252.81, 47.2 or 382.1, as applicable; “Insolvency Proceedings” means a receivership, insolvency, liquidation, resolution, or similar proceeding; and “U.S. Special Resolution Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇ Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

If you are in agreement with the foregoing, please sign two counterparts hereof and return one to each of Citibank and the Issuer, whereupon this letter and your acceptance will become a binding agreement among Citibank, the Issuer and the several Underwriters.
